The thing about writing trans characters is that it is 100% guaranteed that at least a few trans people are going to be unhappy with whatever you write — not necessarily through any fault of your own, though that is certainly a possibility, but because there is such a dearth of trans representation in general.
Trans people are hungry and we’ve mostly been getting by on crumbs. I’m not saying that there are NO media with trans characters, but you have to admit that there are not a lot of really good things to read/watch/consume that have trans characters (and this is without getting into the question of whether or not those characters or the media they’re presented in cater to your particular tastes!)
^ This is usually the real problem. Certain genres and mediums have it worse, too! Think about how expensive it is to make movies or TV shows and how many people you have to get approval from and how many people need to be hired and paid to make one that makes it to cable, streaming services, or theaters, as an example.
Books and comics give us more to choose from in part because the barrier to pushing one out into the world is lower, though still not as much as I would like.
Personally, I want to make a TV show, but I can’t. So, I’m making the story into a comic that could maybe get adapted someday. This brings us close to my point:
Two of the protagonists (and many more of the side characters) in my current project are canonically trans. To some people, these two will be refreshing / the representation that they have been waiting to see for AGES. Those people will feel like they are being presented with a feast. To others, it will feel like being handed an empty plate and told to eat up. Those people are not wrong and I will not take it personally. The way that my writing makes them feel will be extremely real and undeniably valid.
What I want fellow writers to understand is that these feelings are not always going to be the fault of the individual author of the individual project that inspired these feelings (with the caveat that it does kind of suck when a new fictional trans person turns out to be exactly like all the other crumbs we’ve been forced to call a feast.) The people you make angry by breaking away from the norm could simply be mad because they’re used to feeling seen rather than because you've done something terrible.
People will be angry if a trans character is conventionally attractive or if they aren’t. They’ll be angry if you make the character pre-everything, non-op, HRT only, 10 years into a “do everything” transition, fat, thin, tall, short, etc. They’ll be angry if you make the character gay, straight, bi, pan, aro, ace -- I could keep going, but I won’t.
My point is that while you should definitely take the reasoning behind the anger your work may inspire into consideration and you should ABSOLUTELY remain critical of your own work if you want it to be the best it could possibly be...
You also have to be aware that you CANNOT please everyone, especially not with a single trans character in isolation, and you should not work yourself half to death trying to meet some imaginary guidelines of what “good” representation is, because it doesn’t exist.
"Good representation" means something different to everyone.
Also, someone already made basically what I was trying to express in this post but better and also in a single image:
